Specification of Letters Patent.

Application filed December 2, 1909. Serial No; 531,041.

To all whom it may concern:

Be it known that I, FREDERICK G. KING, a citizen of the UnitedStates,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain Improvements in Machines for Use in theManufacture of Boots and Shoes, of which the following description, inconnection with the accompanying drawings, is a specification, likereference characters on the drawings'indicating like parts in theseveral figures.

This invention-relates to machines for use in the manufacture of bootsand shoes and is herein embodied in a machine for use in applyingpressure to a shoe and thereafter operating upon the shoe. In theparticular instances illustrated, the machine is arranged to applypressure against the side of a lasted and welted shoe at or adjacent tothe rear end of the welt and the front end of the heel seat for forcingthe shoe stock into snug relation to the last and for holding it in suchrelation while-a tack is inserted into the upper and innersole on theshoe bottom for securing the stock. This operation is related .to theshoe lasting operation and is required in the manufacture of good weltshoes because there is necessarily a space at eachside of the shoebetween the permanent upper fastening tacks of the heel seat and theends of 'the'permanent upper fastening seam or inseam, as it is called.This space is left because the sewing machine canno-textend the seam allthe way tothe ends of the row of heel seat tacks. If this uppertightening and securing operation is not performed before the liable tospread at these points'during the attaching operation or duringsubsequent Wear and give to the shoe a loose and ill fitting appearanceat the front ends of'the heel stiffener. I I

The present invention'while embodied in a machine particularly adapted.for doing embodiment in different machines.

An important feature of the present invention consists in means, in amachine of the class described, for insuring a predetermined degree. ofpressure upon the shoe beforethe subsequent operation for which themachine is arranged can be performed, In the illustrat'ed machine thisfeature of the invention is embodied in means arranged to require apredetermined amount ofv pressure to be exerted at the side of the shoebefore the fastener can be inserted for securing the stock in thepositionto which it is pressed.

This illustrated arrangement. is characterized by two features either ofwhich alone -may, in some instances, be employed. In'the first place,the parts are so arranged that a predetermined pressure must be appliedin order that the shoe may be moved from the uppertightening positioninto the proper field of action or the correct position for the tackerto insert the fastening where it will hold the shoe stock. -Also, asherein shown,-

this displacement or movement of the shoe.

permitted whenthe pressure has been at tained, is arranged to effect thestarting of the power driven mechanism, which, in this machine, isemployed for inserting the securing tack but which in other machines,comprehended in this. invention, mightfbe employed for driving any toolor device for effecting a further operation upon the shoe.

-Other features of the-invention including certain details ofconstruction and ,combinations of parts will be explained in connectionwith the following description'of the machine and 'will then bepointedout in the claims. i

'Figure 1 is a side elevation of a machine embodying this inventiondnthe best, form now known to me: Fig. 2 is a perspectiveview arranged toillustrate particularly the new features of the machine.

The machine comprises a head or fixed frame-work 2 upon which isjournaled a cam shaft-4 driven by aclutch which comprises a loose pulley5 and a cooperating member 6 which is fast to the shaft and withrelation to which the pulley'5 is movable axially into and out ofdriving engage -ment.'- This'axial movmentof the clutch member 5 iseffectedby. the spring 8 through a lever 10 pivoted at its lower end tothe head and operatively connected to the pulley for moving the latterfrom and toward the clutch member 6. The lever is normally locked infitsretracted position with the clutch members disengaged by a controllinglever 12 having on its rear or-left-hand end, .Fig. 1, an abutmentarranged to engage a small abutting face oil the lever 10. The

roe inns tack supplying mechanism to deliver tacks movement from thehopper 23 through the raceway 2-1 into position to be inserted by thedriver.

The pressure applying arm or upper tightening device 25 is mounted forendwise in the. head of the machine against the resistance of theforwardly act.- ing' spring 26. The arm is shown as formed in twosections pivotally connected by the ping? to permit the outer end of thearm to be moved vertically toward and from the tacker, its lowerposition being determined by an adjustable screw 28 against which it isnormally held by a leaf spring 31, in Fig. 2. The nozzle of the tackeris preferably stationary and by reason of the provision for verticalmovement of the up per tightening device the shoe stock may be firmlycompressed between the nozzle and thelast before the tacker is caused toinsert the fastening tack, as well as forced inwardly over the edge ofthe last to tighten it by reason of the displacement of the tighteningdevice laterally with relation to the direction of movement of thedriver. The arm 25 has on its front end a suitably shaped work engagingmember 30 which may be pivotally mounted and formed as shown to extendinto the welt crease and to press against the upper at the side of theshoe near its edge for forcing the shoe stock into snug relation to thelast. The pressure arm 25 also has onone side, see Fig. 2, a lug whichmay be the head of the pin 27 within which is adjustably mounted thethreaded pin 35, the inner end of which is tapered, as shown in dottedlines. This pin is arranged to overlie an inclined face on the stem of avertically movable block 36 upon which is pivotally carried the-trippingdevice 15. This arrangement provides that when the pressure determinedby the adjust men-t of the spring 26 has been applied through the"lastagainst the arm 25 for tightening the upper, the arm will no vc and,through the block 36', pull down the i tripping device 15 and the rearend of the clutch controlling lever 12, thereby permitting lever 10 tobe moved by its spring 8 for closing the continuously driven 'clptchmern her 5 against the fast clutch member to cause the tacker to beactuated i ickwardly carrying with it the taper pin The clutchcontrolling devicis full;

cruined upon a sm, h l end of whiqh has a cam groove by which sale.

the controlling device are moved for ardly during the rotation of thecam shaft to withtrolliug lever from under the hook see i. The spr Vraises the controlling lever as soon. as it is freed from the trippingdevice and in the further rotation of the cam shift the controllinglever moved rearwardly to ra l ng ge the lever 10 and separate theriutch members at the end of one rotation of the camshaft during which a2, of the tri iping device tacit. has been driven and {mother tacitsupplied in position to be driven at the rent machine,operation. Thetrippin hozvever held down until the w the shoe on arm is relieved r i dthere is no possibility of the maclnne making a. sec ond revolution anddriving a second tack until the shoe has been moved outwardly to let thearm 25' and the tapered screw 33 come forward again. The device or lever15 has a tail-piece arranged to engage a.

stop stud ll and the hooked head of the tripping device 15 is bevelethas shown in Fig. 2, to cause it to tip bacltwardly as is raised by thespring 3 to rard position for reengaging lever 12 after the pressure ofthe shoe against thearin has been relieved and the spring 26 permittedto force said arm and the taper pin 35 forwardly.

The nozzle 45, through which the tacit is drivem is herein shown as-ofpeculiar form in that it has a rearward extension or lip 46 whichextends bEtCkWtUiClly far enough. to prevent the possibility of theendwise movable pressure arm ever rising above the lower end of thenozzle and becoming vaught against it as might otherwise happen when theshoe stock-in the rear of the welt end is presented against the arm. Itis sometimes desirable to do this for tightening and securing the shoestock farther back than the welt extends. I
